Pete'n'ted May 4, 1909.

Application filed May 12, 1908. erial No. 432,546.

T 0 all whom it may concern:

Be it known tl at I, FRANCIS NA'rnER, of Johnstown, in the county of tainbria and State of Pennsj'lvs. .iia, have invented a new and useful lniprovenient in Switch Structures, of which the following is a. full, clear, and exact. description .t' ience heinghad to the accompanying d1 ..\\'ings. which form a part of-this specification.

My invention relates to that type of switchstructures known as tongue switches in which; a" ngue is pivotally mount-ed in the switch st The ohjec simple .and 'ellic en-t device whereby the heel or pivoted end of the tongue is held to its seat in the switch structure by means of an adjustable device whereby the wear of the heel of the tongue can he taken up.

W 1th these ob ects in vievgniy inventionconsists in the novel construction, arrange ment and coniljlination of parts pointed out in the appended claims, and illustrated in the accompanying drawings in which s Figure l, is a plan view oi" a portion of a switch structure embodying m invention; Fig' 2 is a section on the line li -il of Fig. 1 Fig.3 is a similar view on the line illill. of

with the usual tread and guard surfaces.

(1 is the tongue bed which is provided with an enlarged circularrecess a.

B, is the switch tongue having an enlor circular heel b, and-projecting therefroni'fisa lug b having portions cut away, as at W, forming recesseslor the purpose hereinafter This tongue i3, is placed on the seat a of the switch structure A, and its circular heel b, is ro'tatohly mounted in the circular recess 0/, with the projection '1) extending through an orifice in the switch structure into a recess 0. below the tongue bed. Mounted within this recess (1 is the lever C, which is fulcruinod on the pro ection 'a 0n the switch structure A. T he one end having the jam nut D. The forked end C" enters the cutaway portions 5 of the projection I) of the tongue B.

When the arts are completed and ready be assemh ed, the tongue is dropped nto y invention is to provide a its position, and the lever O is inserted into its position. The screw D is then put into the one end of the lever and screwed down to its proper place of adjustment after which the join nut is run down to retain. the screw in its position. As will readily e understood lay reference to 2, the screw has a tendency to raise the one end ofuthe lever, thereby depressing tne forked end 0, and with it the heel of the tongue. As the heel of the tongue heroines worn, the jam nut D is released, and the screw D is turned to elevate this end of the up the wear at the heel of the tongue, after which the nut is again set to lock the screw D. l"o provide ready access to the screw D, removable cover is provided for the opening which is in communication with therecess o in the switch structure.

I do-not wish-to liznit myself to the detail construction as shown and claimed, as various changes can be made, without departing from the spirit of my invention. Having thus fully described my int Lil;

" what I claim as new, and desire to secure oy Letters Patent, 1s:

therein, a fulcru'med lever, one end of which is in engagement with the tongue, and means to exert pressure on the other end to hold the heel of the tongue down.

3. in o. switch structure, a tongue having a projection extending below the oottom of the tongue bed, a lever, one end of said lever engaging the projection, and a screw to raise the lever passing through the other end thereof.

- 4. In a switch structure, a movable tongue having a projection mounted thereon, said projection being rovided with cutaway portions to receive t e lorkedend of a lever, one end of said lever being provided with on adjusting screw.

In-testimony whereof, I have affixed my signature in presence of two Witnesses.

FRANCIS NATHER.
